Air travelers are not facing heightened security at DIA and other U.S. airports in the wake of the death of Osama bin Laden.

"We remain at a heightened state of vigilance, but the Department of Homeland Security does not intend to issue a NTAS alert at this time," Homeland Security Director Janet Napolitano said in a release.

The department scrapped its color-coded alert warning system on April 20 and now issues what it calls National Terrorism Advisory System alerts.

Those alerts are clear statements that there is an "imminent threat" or "elevated threat" of terrorism. An imminent threat warns of a credible, specific, and impending terrorist threat against the United States. An elevated alert warns of a credible terrorist threat against the United States.

"I have been clear since announcing NTAS in January that we will only issue alerts when we have specific or credible information to convey to the American public,' Napolitano said. "However, our security posture, which always includes a number of measures both seen and unseen, will continue to respond appropriately to protect the American people from an evolving threat picture both in the coming days and beyond."

At mid-morning, passenger traffic at Denver International Airport was light, and there was no visible evidence of enhanced security.

Lines at security checkpoints were short and screeners were making full use of TSA's full-body scanners.

A few passengers received pat downs from screeners.

Dawn Doty, of Boulder, was traveling to Atlanta on business and said she was not more apprehensive about flying in the wake of bin Laden's death, nearly 10 years after the 9/11 attacks.

"Since the time that happened, so much has changed with security," Doty said. "We're a pretty buttoned-up country. I feel safe flying."
